Coastal Water Management Challenges

The video discusses the ongoing battle against saltwater intrusion in California due to drought. It highlights the efforts of the Soquel Creek Water District to combat this issue by using hydraulic barriers and treated wastewater to recharge groundwater. The video also covers the use of Airborne Electromagnetic (AEM) technology to map saltwater intrusion, a collaborative effort with a Danish company. The data collected helps prioritize areas for groundwater recharge, aiming to secure water supply amidst climate change challenges.

What is the main issue affecting the beaches around the Capitola Santa Cruz area?

• Overcrowding by tourists

• Pollution from nearby factories

• Erosion of the coastline

• Saltwater intrusion into freshwater wells

What is the primary method used by the Soquel Creek Water District to combat saltwater intrusion?

• Building seawalls

• Pumping treated wastewater into the ground

• Reducing water consumption

• Drilling new wells

What is the main goal of creating a hydraulic barrier using treated wastewater?

• To increase water pressure

• To reduce water usage

• To prevent saltwater from entering freshwater wells

• To improve water quality

What technology is used to map the geology beneath the shoreline?

• Satellite imaging

• Seismic surveys

• Airborne Electromagnetic (AEM) surveys

• Ground-penetrating radar

What challenge does the AEM technology help address along the coast?

• Identifying tourist attractions

• Tracking fish populations

• Locating saltwater intrusion

• Measuring air pollution

Which organization partnered with a Danish company to enhance AEM technology?
